Fix-up the Fixtures and Appliances
Another way to save water without a lot of hassle is by making some simple fixture upgrades. For example, try installing low-flow showerheads in every bathroom and faucet aerators at all of the sinks. You should be able to find a number of quality fixtures available in the $10 to $20 range, and according to the U.S. Department of Energy, they can help you net a water savings of anywhere from 25 to 60 percent. Look for those that offer a gallon per minute rate of 2.5 or less.
Also, consider replacing your old appliances, such as dishwashers and washing machines, with high-efficiency versions marked with an ENERGY STAR® logo. Swapping out your toilets with new ones that carry the EPA's WaterSense label may help, too. Though these fixes typically require a larger financial investment up front, the long-term savings could make up for it. For example, the EPA says a WaterSense toilet can save about 4,000 gallons of water per year.
